3. George Clooney: The actor, who isn't afraid of speaking out about even the most heated political topics, took part in a Los Angeles play called 8, about the court battle to overturn California's gay marriage-banning Prop 8.

The actor famously said, "At some point in our lifetime, gay marriage won't be an issue, and everyone who stood against this civil right will look as outdated as George Wallace standing on the school steps keeping James Hood from entering the University of Alabama because he was black."

4. Ellen DeGeneres: The ever-popular funnylady has been a gay rights advocate since coming out of the closet on television in front of millions of viewers in 1997.

For more than a decade, DeGeneres has supported countless celebs who've done the same and has been ranked on the top of Out magazine's Power Lists for years.

She tweeted today, "It's a supremely wonderful day for equality. Prop 8 is over, and so is DOMA. Congratulations everyone. And I mean everyone."
